Answer 1

参考demo：

import window from '@ohos.window';
@Entry
@Component
struct Index {
  @State screenHeight: number = 0;
  aboutToAppear() {
    window.getLastWindow(getContext(this)).then(currentWindow =>{
      let property = currentWindow.getWindowProperties();
      let avoidArea = currentWindow.getWindowAvoidArea(window.AvoidAreaType.TYPE_KEYBOARD);
      // 初始化显示区域高度
      this.screenHeight = px2vp(property.windowRect.height - avoidArea.bottomRect.height);
      // 监视软键盘的弹出和收起
      currentWindow.on('avoidAreaChange', async data => {
        if (data.type !== window.AvoidAreaType.TYPE_KEYBOARD) {
          return;
        }
        this.screenHeight = px2vp(property.windowRect.height - data.area.bottomRect.height);
      })
    })
  }
  build() {
    Row() {
      Column() {
        Text('请输入短信验证码')
          .fontSize(30)
          .margin({
            bottom:'50'
          })
        TextInput()
          .width('70%')
          .height('150px')
          .margin({
            bottom: '30'
          })
        Button('确定')
          .width('70%')
          .margin('20px')
      }
      .width('100%')
    }
    .width('100%').height(this.screenHeight)
  }
}
